4-Methylcyclohexanol, 4-methylcyclohexanone, methyl-cyclohexane
and toluene or a mixture of all can be efficiently produced from p-cresol
when hydrogen is applied as a reductant over carbon and alumina supported
Pt, Pd and Ru catalysts under high pressure and high temperature. Non-noble metal catalysts such as Ni–P, copper chromite, MoP and MoS have been applied as well.
